Eig. jmay-be of vthe samegeneral constme tie i ae th 13 eft 17? of? thedeviee shown in dwiith the-elbiiggafed aperture 20 a,

inclusive, my improved device is mounted with the spring part 18directed inwardly of the window frame or at right angles to the verticalplane of the window frame, and in the use of the device after the shank13 has been placed in the aperture of the keeper 14, the shank 15 ispassed over the curved end portion 25 of the spring part '18 and forcedinwardly, in which operation the spring is depressed and the shank 15passes through the aperture 20 and into the aperture 27, and the springpart 18 then moves outwardly to lock and retain the shank 15 againstdisplacement in the device 16. When it is desired to remove the shaderoller the spring part 18 is depressed by hand and the shade roller isremoved as will be apparent.

In Figs. 4:, 5 and 6 of thedrawing, I have shown a slight modificationin which the spring part 18 instead of being attached to the part 17,and instead of being provided with the looped portion 25, is curved atone end as shown at 28 and provided with an enlarged cross head 29, theopposite ends of which are apertured and the crosshead 29 is of suchform as to register the apertures thereof with the apertures of the ears23 of the part 17 so that the passage of nails, screws, or the likethrough the apertures of the ears 23 will operate to retain the springpart 18 as well as the part 17 in predetermined position, It will alsobe noted that the device shown in Figs 4 to 6 inclusive is mounted in anangular position on thewindow frame, or one of the side members 11thereof, or at an angle of approximately forty-five degrees to thevertical plane of the window frame instead of at right angles as shownin Fig. 2 of the drawing. \Vith the above exceptions the constructionand operation of the device shown in Figs. 4 to 6 inclusive will beexactly the same as that shown in Figs. 1 to 3 inclusive.

In Fig. 7 of the drawing, I have shown another modification in which Iemploy substantially the same spring ,part.18 as shown in Figs. 4 to 6inclusive, but in Fig. 7 the part 17 or the aperture 20 thereof opensoutwardly through the opposite side of said part 17 as shown at 30, andwith a device of this construction it is supported in a window frame oron one of the side members thereof with the spring part 18 in the samevertical plane as the window frame and with thefree or projecting end ofthe spring part directed downwardly. -It. will be apparent that withthis form of construction the shank 15 of the shade roller is passeddownwardly into the device and is automatically passed into the aperture27 v of the spring part 18, and said shank is released by depressing theprotruding, end

portion 26 of the part 18.

From the foregoing it will be apparent thatthe'distinctive features ofmy present invention over that shown and described in my pendingapplications are the provision of a comparatively short part or casing17 and a correspondingly short spring device effecting a decided savingin the amount of material employed in the production of my improveddevice and also permitting of the mounting of the device onsmall fiatsurfaces on the side 7 members of" a window frame, and while I haveshown certain details of construction for carrying my invention intoeffect, it will be understood that I am not necessarily limited to thesedetails, and Various changes therein and modifications thereof maybemade, within the scope of the appended claims without departing fromthe spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as'new and desire tosecure by Letters Patent, is

1. A lockdevice {for the shank of shade rollers comprising a casing, thefront wall of whichis apertured, and apart composed of resilientmaterial mounted within the casing and apertured' to register with theaperture of the casing.

2. A lock device for the shank of shade I rollers comprising acasing,the front wall of which is apertured, a part composed ofresilient material mounted within the easing and apertured to registerwith the aperture of the casing, and the aperture of the casing openingoutwardly through one side thereof to permit of the passage of the shankof a shade roller into said aperture.

3. A look device for the shank of shade rollers comprising a casing, thefront wall of which is apertured, a part composed of resilient materialmounted within the easing, the aperture of the casing opening outwardlythrough one side thereof to permit of the passage of the shank of ashade roller into. said aperture, and one end of said part being fixed,and the free end portion of said part being slightly curved where theaperture opens outwardly through the casing to permitof the passage ofthe shank of a shade roller thereover. I

4. A lock device for the shank of shade rollers,'said device comprisinga casing having an elongated aperture openingoutwardly through one sidethereof, means whereby said casing may be attached to a suitablesupport, and a spring member within said casing and having an aperturetherethrough registering with the aperture of said casing.

5,.
